Abstract Herein, magnesium metatitanate (MgTiO 3 ) ceramics were synthesised using recycled magnesia-hercynite (MH) bricks as the raw materials to achieve solid waste reusing of cement kiln refractories. The MH mixed with anatase TiO 2 investigate effect addition doped B O during synthesis MgTiO at 1400 °C. Phase compositions and microstructural studies performed x-ray diffraction (XRD) scannin...

The temperature dependences of the structures of rutile and geikielite are reported up to ~1200C. While the thermal expansion of the unit cell edges for our rutile agree with published data the (Ti-O) bond expansions show significant differences with the longer (T-O) showing a larger thermal expansion coefficient (19.3 x 10 /degree) than the shorter bond (2.6 x 10 /degree). High-temperature cry...

Abstarct  In this paper, effect of mechanical activation on microwave reactive sintering of MgO - TiO2 system was investigated. Mixtures of MgO and TiO2 were milled at different times. Mixed powders along with 10 h milled powders were chosen for microwave sintering between 1000- 1400⁰C. Results showed that increasing of temperature up to 1400̊C for mixed powders could not give rise to complete f...
